From Food Waste to Roadways: Using Compost to Improve Soil Conditions and Tree Success Along Highways

Planting trees along highway roadsides is a good way to increase tree coverage in cities, but getting trees to grow here and maintaining these plantings over time can be difficult. Reducing soil compaction and adding organic material, such as compost, can improve roadside soils and support tree growth in these areas. A 5-year study in Ontario recently found that loosening up the soil and mixing in 10-25% food waste compost relative to soil can help improve tree growth along roadsides, possibly reducing the need to follow up and maintain these trees over time.

Disposal Method Matters: The Truth Behind Biodegradable Plastics

Biodegradable plastics are being introduced as a solution to the buildup of plastics in the environment, and they are often touted as being an environmentally-friendly option. However, they come with their own complications. Researchers have investigated how specific biodegradable plastics break down (or don’t) in different environments, showing that how they are disposed of makes a big difference in how environmentally-friendly they are.

Growing food with garbage – how fertilizing crops with food waste could solve the problem of finite landfill space

Much of the organic-rich waste (e.g. food scraps, yard waste) that ends up in landfills could be put to better use, like building soil fertility for crops. A recent study suggests that crops grown in soils that have been amended with a variety of landfill-destined organic waste products produce comparable yields to plants grown with conventional synthetic fertilizers.
